Chemical stripping should be carefully researched as
a removal method for soft wood (e.g., pine or
redwood) substrates. The wrong chemical strippers
can increase the risk of residual lead contamination
in the substrate.
2. Steel and Metal Surfaces (Industrial)
a. Power/Hand Tool Cleaning (least acceptable)
b. Dry Abrasive Blast with Water Ring (Wet "Halo")
c. Wet Abrasive Blast
d. Low Volume High Pressure Water Blast
e. Chemical Stripping
f. Vacuum Blast
The following practices are restricted during lead
hazard abatement work on housing per 40 CFR 745:
Open flame burning or torching is prohibited;
machine sanding or grinding or abrasive blasting on
LBP is prohibited unless used with High Efficiency
Particulate Air (HEPA) exhaust control; dry scraping
in conjunction with heat guns, or around electrical
outlets, is permitted if limited to no more than 2
square feet in any one room (20 square feet on
exterior surfaces); heat guns must operate at a
temperature below 1100 degrees Fahrenheit.

NOTE: For lead hazard abatement work in housing or
child occupied facilities, consult the risk
assessment report to select abatement or interim
control techniques to be used in target housing.
For commercial/public buildings and industrial
buildings, the designer will have to ascertain
appropriate procedures, methods and techniques to
control lead hazards. The use of encapsulation,
enclosure, or soil barriers as an abatement/control
system requires the input of engineering/
architectural experts familiar with these controls.
Encapsulation should not be specified for areas
where water damage exists or could easily occur.
The designer may need to test the existing
substrates to ascertain that encapsulation is
feasible at all. Methods listed or taken from the
1995 HUD Guidelines may be considered. Add
additional paragraphs to address unique local or
state requirements.
**************************************************************************
Provide methodology for LBP/PWL [removal] [abatement/control] and processes
to minimize contamination of work areas outside the control area with
lead-contaminated dust or other lead-contaminated debris/waste and to
ensure that unprotected personnel are not exposed to hazardous
concentrations of lead. Describe this LBP/PWL removal/control process in
the LBP/PWL R/CP. [
